<!-- $$$qtopenglextensions.html-description -->
<div class="descr"> <a name="details"></a>
<p>QtOpenGLExtensions is a library that contains auto-generated wrappers for OpenGL extensions from the Khronos registry.</p>
<p>To include the definitions of the module, use the following directive:</p>
<pre class="cpp">

  <span class="preprocessor">#include &lt;QtOpenGLExtensions&gt;</span>

</pre>
<p>To link against the module, add this line to your qmake .pro file:</p>
<pre class="cpp">

  QT <span class="operator">+</span><span class="operator">=</span> openglextensions

</pre>
<p>Because applications do typically use only few extensions, the library is statically linked with the application. To avoid issues with <a href="lgpl.html">GNU Lesser General Public License (LGPL)</a> in this case, the library is licensed both under the commercial licenses, and the <a href="https://spdx.org/licenses/BSD-3-Clause.html">BSD 3-clause &quot;New&quot; or &quot;Revised&quot; License</a>.</p>
